.To 1l/whom i may concer/i: l 1 I Be it known that I, WILLLAM FRANCIS(iiiiis, ai citizen of the UnitedStates, resid-' ing' nl,Philzidelpliiinin the county of. Phiiadolphin. und Stute oi'Pennsylvanie, have in von ted f'ei'tiiiu new und useful Improvements iii(hisolene liiie-Engiiies; of which the foilouing is :i speciiiciitioii.l

)iov invention relates to improvement-S in iii-e ei eincs undparticularly to those engines in which gzisolciie is .used its themotive power for operating the pumps.

The elije-et ol' niy invention is to provide e light, strong :indduriihle fire engine of high olliciciicv :ind power :ind such es een beinsteiitiiiicously started.

.k further object ol' iiiyin'vention is to construct ii. fire enginehaving e ges engine1 pro'- 'vided with u pluiailit)v of single orvdouble l' ect-ing cylinders.

A still further object oi' niy inveiitionis to so tiri-:iii lre theports that Vthe iiiziin drivingsliaft iiil extend longitudinally withthe tire engine. Y

A still further object of niy invention is to provide one or more rotarypumps, Idriven )y directv gearing freni the inein driving--V A stillfurther object ol' iiiy invention 'is to provide e single-freine for theengines end pumps.

A still further object oi niy invention is to provide a. wnter-jecketto'piotectthe gesoene reservoir.

The engine consists of e plurelity et cylin i have shown six f ders 10,in the drawings oyinders in which en expiosion titlies pine o et both"ends ot' the cylinders. 4'.the engine ironie l2 rests upon the'iniiinbcenis'nnd and carries the ninin driving-shift i5 of thel engine, whichextends lengthwise of the" i'aine. By; so eoiistruetingthe freine theengine :ind punips aire supported in such si infinner that einlxvise.oseilhitiens aire avoided 'und by having the'driving-sheft extending.

lengthwise of theirs-nie any iiuiiiberfoi eyliiidei's iiniy be edded tothe engine.

In the firewiiigs I have shoivn rotry p'uii'ips out any other typeii'iny .be us'ee. The seid pumps 16 end 1S are nioiinted on the pumpbese oiv` housing 2G, which is sup# ported on the mein beams .5l end 6..'Efieh` of the pumps is provided with two-piiiiip shafts 21 and 22,coupled together by geerwheels 23 en (i124 atene end and et the otherend bv-gezir-wheels 25 end 26, thus insuring "u.- unil'orni inotioiit-'o bothshiri'ts.

The mein driving-shaft 15 of the engine is provided with gear-wheeis 28and 30, the' former 28,'i`neshing with ve gesr-whee1 29 on the puinpshaft 22, of the .pump 15, end the letter, 30, meshing WitheJ gear-Wheel31, on:

provided with' e viiive 3S), by ineens of' Whieh'tl'ie Weter from yonepump may be discharged through the outlet of the other pump, and thewater from bloth pumps muy then belfoiced out of the disehergei'outietof one pump. The hose iney be eoupied to the outlet of both of thepumps, and Wlienthe valve 39 is openit will equeiizethe pressure oftheWater. When ii high press re oi weter is desired the valves 39 und #l ,1are closed sind. the valve 35 opened so that the water will flow fromthe puinp i8, through the pipe 37, to the inlet lolf piiiiip i6. Thepresv sure of the waiter will then be ege-in raised by the iic'tion ofthe pump 16, above the pressure exerted by the puinp '18.

The Water-jackets of the cylinders l0 ofy ioo le the oylind in thepumps. The water cn'- 'irougi pipes 46 and 47, by ne pump driven fromthe main driving-shaft i and the Water returns from the water-jackethrough the pipe 49, to the Water ik A. compressed air tank 50,connected with iti), by a pipe 60, is provided for the purpose ol'starting the engine: NAn air pump i, driven from the man1 drivingshaiti5, forces into the air tank 50.

The space bee cased in an outer casing 53. twin" the tank F Ll and theouter easing.; 53 is supplied with Witter, tnrough the pipe fromthepi'inips. An overriow pipe 55, is

an rovioed so that the water will circulate and ieep the oil tank Icool, when the 'ire engine is in close proxi y to a fire.

Tine gasoiene carried from the tank 52 through the pipe 56 to thecarburetor 57,

from which it drawn into the cylinders,

through the pipe 58, in the usual manner.

Ey the arrangement of the direct gearing between 'the main driving-shaftoi the engine und the pumps, the necessity of inter- :'50 posing aclutch between the engine and the pumps is avoided, thus theconstruction is sinipliied.

Either double or sinule acting' eiwines ma Y n u i.' n be used withoutdeparting .trom my invention and in piace ol having the two pumps`arranged side by side they may be placed in line and nur-.interi on thesame pump shafts. The pumps may be either the rotary or centrifugal typewithout departing trom my inl10 vention.

Having thus described my invention l claim and desire to secure byLetters Patent:
